Abstract The formation and stability of collisionless self-gravitating systems is a long standing problem, which dates back to the work of D. Lynden-Bell on violent relaxation, and extends to the issue of virialization of dark matter (DM) halos. An important prediction of such a relaxation process is that spherical equilibrium states can be described by a Fermi-Dirac phase-space distribution, when the extremization of a coarse-grained entropy is reached. In the case of DM fermions, the most general solution develops a degenerate compact core surrounded by a diluted halo. As shown recently, the latter is able to explain the galaxy rotation curves while the DM core can mimic the central black hole. A yet open problem is whether this kind of astrophysical core-halo configurations can form at all, and if they remain stable within cosmological timescales. We assess these issues by performing a thermodynamic stability analysis in the microcanonical ensemble for solutions with given particle number at halo virialization in a cosmological framework. For the first time we demonstrate that the above core-halo DM profiles are stable (i.e. maxima of entropy) and extremely long lived. We find the existence of a critical point at the onset of instability of the core-halo solutions, where the fermion-core collapses towards a supermassive black hole. For particle masses in the keV range, the core-collapse can only occur for Mvir ≳ E9M⊙ starting at zvir ≈ 10 in the given cosmological framework. Our results prove that DM halos with a core-halo morphology are a very plausible outcome within nonlinear stages of structure formation.

The core problem of teaching English as a second language at transport university is students’ poor knowledge of vocabulary. Current solutions to the given problem such as providing word explanations and repetitive practices are ineffective. We strongly believe that the mindmapping technique proposed by Tony Buzan as a note-taking method is a novel, yet an extremely potent tool that aids students in enlarging their professional word stock by associating new vocabulary to their existing knowledge using colors, images, symbols, etc. As might have been expected, the findings of our study point towards the idea that the strong visual appeal of mind maps created by easy-to-use software boosted the educational process and helped students of the experimental group memorize more new words in contrast to students of the control group.

Tourism Organization

The purpose of the article is to explore and describe the resources made available by the United Nations World Tourism Organization (UNWTO) during the COVID-19 pandemic and discuss their role in fostering knowledge and promoting awareness in society. The resources are examined using a conceptual model of website evaluation proposed by Li and Wang (2010), which has been adapted to be applicable to the organizational context of UNWTO. The findings show that the UNWTO website resources can be divided into two categories: resources related to the COVID-19 pandemic, e.g. information about existing special groups, and resources connected with the core mission of the UNWTO, e.g. important events from before the pandemic or the organization’s main goals. There are new interactive tools, developed specifically in relation to the pandemic, with relevant data for those involved or interested in the tourism sector. The resources are freely available, easily accessible, abundant, varied and highly informative. The UNWTO website is a gateway to knowledge, providing information about, reasons for and effects of relevant actions of the organization, e.g. raising awareness of the importance of both the pandemic problem but also tourism itself, securing considerable funding for the tourism sector by making world leaders aware of the facts and the importance of tourism, or promoting safe travel measures and encouraging actions aimed at accelerating the recovery of the tourism sector.

Hands On

The current project management literature seldom addresses the leadership and management strategies used in educational project. The knowledge specialized for workshop-based educational project is even more limited. As one of the most complicated educational projects, this chapter aims to define what workshop-based educational project and its uniqueness is, examine the concerns in such workshop and analyze possible roles of project manager through the case study of the environmental sustainability project. The parties involved and their relationship in work are also clearly revealed. Six unique concerns which specifically exist in such kind of project and five roles of its project managers are identified are discussed and explained by using the case study. It is hoped that the discussion in this chapter is able to give references for educators or administrators who plan to hold projects which involve hands-on workshops as the core of educational activities.

The Given

For a given set of points in the Euclidean plane, a minimum network (a Steiner minimal tree) can be constructed using a geometric method, called Melzak's construction. The core of the Melzak construction is to replace a pair of terminals adjacent to the same Steiner point with a new terminal. In this paper we prove that the Melzak construction can be generalized to constructing Steiner minimal trees for circles so that either the given points (terminals) are constrained on the circles or the terminal edges are tangent to the circles. Then we show that the generalized Melzak construction can be used to find minimum networks separating and surrounding circular objects or to find minimum networks connecting convex and smoothly bounded objects and avoiding convex and smoothly bounded obstacles.

The article is devoted to the consideration of the features of the verbalization of the concept HAIR in the English language. The purpose of the work is to examine the structure of the English concept HAIR as a fragment of the English-language picture of the world of the English-speaking society. The main attention is focused on the analysis of the language embodiment of the given concept in the naïve and professional varients of the picture of the world. The English concept HAIR is a fragment of the conceptual picture of the world, which is reflected in the language picture of the world, namely in its three fragments, verbalized by the constituents of the lexical-semantic groups, distinguished according to the somatic feature. They are head hair, facial hair, body hair. The analysis of the language and speech material showed that the structure of the English concept HAIR in the naive picture of the world is a three-component formation, which consists of a core, a nuclear zone and a periphery. The core includes such conceptual features as somatic and gender. The nuclear zone includes objective and various associative conceptual features, namely: age, thinness, protection, beauty, strength / success, value. The periphery of the concept consists of socially-identifying functions - professional, religious and social-group. The core of the concept HAIR in the professional picture of the world includes such conceptual features as somatic, gender, structure and development. The nuclear zone includes objective conceptual features, namely: health, age, protection. The periphery of the concept consists of professional, religious, and social-group social-identifying functions. Thus the periphery of the given concept in the two variants of the picture of the world is identical. The prospects for further research are seen in the consideration of the mentioned aspects of verbalization on the material of English artistic speech as well as professional discourse.

Project management has become more than just a supporting role for businesses. For many organizations, it is a relevant part of getting things done, and the many tasks as-sociated with managing projects require more attention than just the scope of work of indi-vidual project management professionals (PMPs). This paper will contribute by showing how through taking standardization as the goal as well as using it internally, the Project management Offices (PMO) will contribute to the maturity level of the organization in terms of project management and increase the sustainability of their business. The core concept of this contribution is the use of Hoshin Kanri (HK) ideas to standardize communication among the process-responsible members at the PMO. Finally, application from a practical point of view is presented and its meaning discussed.

Image captioning is a process to assign a meaningful title for a given image with the help of Natural Language Processing (NLP) and Computer Vision techniques. Captioning of an image first need to identify object, attribute and relationship among these in image and second is to generate relevant description for the given image. So it require both NLP and Computer vision techniques to perform image captioning task. Due to complexity of finding relationship between the attribute of the object and its feature makes it a challenging task. Also for machine it is difficult to emulate human brain however researches have shown a prominent achievement in this field and made it easy to solve such problems. The foremost aim of this survey paper is to describe several methods to achieve the same, the core involvement of this paper is to categorise different existing approaches for image captioning, further discussed their subcategories of this method and classify them, also discussed some of their strength and limitations. This survey paper gives theoretical analysis of image captioning methods and defines some earlier and newly approach for image captioning. This survey paper is basically a source of information for researchers in order to get idea of different approaches that were developed so far in the field of image captioning. Key words : Computer Vision, Deep Learning, Neural Network, NLP, Image Captioning, Multimodal Learning.
